Time pressure gradually corrupts an engineer's standard of quality and perfection. It has a detrimental effect on people as well as products

In the practical world of computing, it is rather uncommon that a program, once it performs correctly and satisfactorily, remains unchanged forever.

I have never designed a language for its own sake.

Programs should be written and polished until they acquire publication quality.

Clearly, programming courses should teach methods of design and construction, and the selected examples should be such that a gradual development can be nicely demonstrated.

Experience shows that the success of a programming course critically depends on the choice of these examples.

I am convinced that there is a need for high quality software, and the time will come when it will be recognized that it is worth investing effort in its development and in using a careful, structured approach based on safe, structured languages.
